The Machines
Free Will Why do we claim that a
machine has no free will? Usually, because a machine can solve only the
problems that we program it to solve. We, on the other hand, can solve novel
problems in unpredictable situations (or, at least, give them a try). And
that's because we can make actions that we have never done before and that nobody
ever told us to do, whereas a machine can only do what it has been programmed
to do. Machines are built to solve
specific problems in specific situations, simply because that is what humans
are good at: building machines that solve specific problems in specific
situations: we humans like to "design" a machine, to write the
"specifications", etc. This is not the way nature built us. Nature
built us on a different principle and it is no surprise that we behave
differently from machines. Since in nature we never know what the next problem
and situation will be like, nature built us as "Darwinian" machines:
our brains generate all the time a lot of possible actions and then pursue the
ones that are "selected" by the environment (the specific problem and
situation at hand). Nature built us on a different principle than the one we
use to build machines. The main difference between our mind and a machine is
their architectures. The lack of free will in
machines is not a limitation of machines: it is a limitation of our mind. If we
built a machine the same way nature builds its cognitive beings, i.e. with the
same type of architecture, it would be a rather different machine, capable of
generating a huge amount of random behaviors and then picking the one that best
matches the current problem and situation. One can even envision a day when
machines built with a "Darwinian" architecture (descendants of
today's genetic algorithms and neural networks) will "out-free will"
us, will exhibit even more free will than we do. After all, most of the time we
simply obey orders (we obey publicity when we shop, we obey record labels when
we sing a tune, we obey our mother's moral principles all day long), whereas a
machine would have no conditioning. And it may be able to generate a lot more
alternatives than our brain does. Free will is simply a folk name for the
Darwinian architecture of our mind that was created by Nature. When we choose
an action, we are actually obeying an ancient command of Nature. We are simply
machines of a different kind than the ones we build. Do we think or are we thought? Back to the beginning of the chapter "Self" | Back to the index of all chapters |
